Large-scale energy spectra in surface quasi-geostrophic turbulence

Chuong V. Tran, John C. Bowman

The large-scale energy spectrum in two-dimensional turbulence governed by the surface quasi-geostrophic (SQG) equation $${\partial }_t(-\Delta {)}^{1/2}\psi +J(\psi ,(-\Delta {)}^{1/2}\psi )=\mu \Delta \psi +f$$ is studied.…
